I'm having similar issues on my Linux Mint 20.3. My onboard sound card (detected as USB Audio) is now broken. The sound coming out is just popping in and out and crackling. My Mainboard is the Z590 AORUS ULTRA. According to the spec sheet, this board used the "Realtek® ALC4080 codec", whatever that means. Hope this helps.
I reverted back to 5.13.0-35 and my audio is working again. FYI SPDIF and 5.1 Surround also did never work with this sound chip / mainboard. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1966432 Title: audio crackling on usb sound card To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1966432/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
